Trump administration officials say the U.S. government knows the location of all children in its custody after separating them from their families at the border and is working to reunite them.
A fact sheet released Saturday night by the Department of Homeland Security also says a parent must request that their child be deported with them. In the past, the agency says, many parents have elected to be deported without their children. That may be a reflection of violence or persecution they face in their home countries.
The fact sheet says Immigration and Customs Enforcement officials have posted notices in all its facilities advising detained parents who are trying to find or communicate with their children to call a hotline staffed 8 a.m. to 8 p.m. Monday through Friday.
